CHARLES RIPPIN, OF ST. LOUIS, MISSOURI.

GRAIN-SCOURER.

SPECIFICATION forming part of Letters Patent No. 451,580, dated May 5,1891. f

Application filed February 25, 1891. Serial No. 382,693. (No model.) l

T0 @ZZ wiz/0m t may concern:

Be it known that I, CHARLES RIPPIN, of the city of St. Louis, and Stateof Missouri, have invented certain new and useful Improvements inGrain-Scourers, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, forming apart hereof.

My invention relates to improvements in grain-scourers; and it consistsin the novel arrangement and combination of part-s, as will be morefully hereinafter described and designated in the claims.

In the drawings, Figure 1 is a vertical section of my machine, taken 0nline .e ,z of Fig. 3. Fig. 2 is a horizontal cross-section taken on theline of Fig. 1. Fig. 3 is aV vertical cross-section taken on the line yy of Fig. 2; and Fig. 4 is a cross-section of one of the spiral Win gsor vanes, showing its corrugated surface and also the small bolts orlugs which pass through the same.

Referring to the drawings, 1 indicates the case or boxing, the samebeing suitably mounted upon any appropriate supports.

2 and 3 indicate parallel shafts, the former of which is mounted insuitable bearings 4 in the case or boxing l. To the shafts 2 and 3, atone end, are secured in any mechanical manner gear-Wheels 5, the teethof which mesh into each other, so that one of the said shafts Will bedriven from the other, and the two shaftswill revolve in oppositedirections,

and to one of the ends of one of the said shafts an ordinaryTbelt-pulley 3a is adapted to be secured to receive a driving-belt fromany convenient power. Encircling said shafts are spiral Wings or vanesG. One of the said spiral Wings or vanes is a right one and the other isa left spiral Wing or vane. The shafts 2 and 3 are placed at such aconvenient distance apartthat the paths of the spiral Wings or vanes Gwill overlap each other, as indicated and shown in Figs. 2and 3. Shaft 3is adjustable relative to shaft 2, and according t0 the peculiar natureand construction of the spiral Wings 6 When shaft 3 is adjustedapproximately close to shaft 2, the Wings 6 will be brought closetogether. By this means it is evident that the distance between thefaces of the spiral Wings or vanes 6 may be regulated, asdesired,corresponding, of course,

to the size of the grain that is desired to be rubbed by them. Theadjustment of shaft 3 is 'effected by thu rnb-screws 7, whichthumbscrews are adapted to move the adjustable bearings S, in which saidshaft3 is mounted. The bearings 8 are movable along in the case 1, asdesired. The spiral Wings or vanes 6 are provided with a series ofsections 9 of parallel corrugations 10, as can be seen by inspectingFig. The sections 9 are arranged segmentally, and each of said sectionsis provided with parallel corrugations, as before stated, and theparallel corrugations of each section being formed at angles with theparallel corrugations of the adjacent sections.

The object of these corrugations is to elevate the grain and spread thesame over the ent-ire `surface of the vanes (3 as the same revolve.

11 indicates lugs or bolts, which are suitably secured in spiral wingsor vanes G. Said lugs are secured in said spiral Wings by means of smallnuts ll, which are adapted to be screwed on the ends of the same. Saidlugs are so arranged in the vanes that the lugs se- `cured in one spiralwing or vane Will pass without coming in contact with the lugs securedin the other wing or vane, as can be readily perceived by inspectingFig. 2. The object of these lugs is to elevate and stir up the grain,and also to increase the friction- -surface that is brought to bear onthe grain.

Said lugs should be of such a size as not to interfere With theadjusting of the spiral wings or vanes 6.

12 indicates a perforated shakeror shifting device, which is locateddirectly beneath the extremities of the spiral Wings G, but not in sucha position as to interfere With the revolving or rotating of the same.is preferably constructed by taking a piece of sheet metal and punchingor stamping it full of perforations of suitable size as to admit thepassage of the dust and small particles of foreign substances that havebeen removed from the grain.

13 indicates springs, one end of which is secured to shaker 12 and theother to the case 0r boxing or to any other part of the device asmechanical ingenuity may suggest. Said springs also have the function ofsupporting said shaker 12 and giving the same a vibratory motion by theagency of a disk 14, rig- Said shaker idly secured at an angle to shaft2, which disk adapted io move between collars lf3, which collars arcrigidly secured to a horizontal moving shaft 17. By this briefexplanation the operation is readily perceived. rlhe disk 14, revolvingas shaft 2 does and being set at an angle on the same, will throw shaft17 in a horizontal direction, which shaft strikes against the shaker 12,and with the agency of springs 13 will give the same a vibratory andshaking motion.

1S indicates an opening through which the grain passes from the shakerinto a spout 19, which leads to anysuitablc receptacle for the cleansedgrain.

2O indicatesa d ust-convcyer,which is mou ntcd in suitable bearings iiithe lower part of box or casing l, the function of which is to conveythe dust and small particles of foreign substances that have beenremoved from the grain out of the box or casing 1 into any desiredreceptacle through a chute or spout 2l. Said conveyer is revolved byabel4 22, which passes over suitable belt-pulleys secured to shaft 2 andthe shaft of the conveyor, as can be readily perceived in Fig. 1.

23 indicates a draft fiue oi'eonduit,onee1id of which communicates withspout 19 or the spout from which the grain passes after being cleansed,and the other end of the same communicates with a fan-box 2l, in which afan 95 is located. Said fan is mounted on a shaft 26, which shaft hasits bearings in a support 27 and also in the draft-conduit 223, as canbe readily perceived in Fig. 1.

2S indicates a belt-pulley which is secured to one end of shaft 2U, andsaid fan 25 is rapidly turned by means of a belt Q9, which passes overbelt-pulley 28 and over a belt-pulley 30, secured to shaft The functionof said fan, of eourse,is well understood; but it would not beinopportuno to give a brief explanation of the same in its connection inthis specificdeviee. Of course, as the grain passes from spout 10 itisbound to contain a considerable amount of dust and chatl", and a draftcaused by the fan will stick or draw the same from the grain and conveyit up the conduit :28. If, perchance, the influence o f the fan shouldattract any of the grain in its passage up the conduit 23 and across thehorizontal portion of the same, the grain, being ofgreater specificgravity than the dust, will fall and may be accumulated in a hopper orreceptacle 31, which is in communication with the draf t-eonduit 23.Said receptacle has secured to it a valve 32, which is held or adaptedto beheld in a closed position by the suction influence of the fan; butwhen sufficient giain has accumulated in receptacle 31 of course suoliaccumulation will open the valve 32 and permit the removal of the grainthat has been accumulated in said receptacle by its own weight.

33 indicates a supplyspout through which the grain may be inserted andbrought in contact with the abrasive influence of the spiral wings orvaries o, and is there oijierated upon by said wings until the frictionhas removed the rust and foreign accumulations, such as incrustationsformed upon the grain. lVlien the grain has been sufficiently operatedupon so as to cleanse it, it then comes in contact with the shaker 2,and the accumulation that has been removed from the grain is sifted outof the saine and falls dowii in the bottom of the box orcasiiig 1, andis there removed, as hereinbcfore stated. 'lhc spiral wings or vanes G,while possessing the function of cleansing the grain, also convey thesaine to opening 1S in the shaker. Before lthe grani is introduced,however, to the abrasive action of the spiral wings or vanes, it should.first be passed through a receiving shaker or sifter and have all thelarge foreign particles removed from it, such as stones, dac.
